Multiple spark gaps spaced apart does help some. Do some modelling in HGDT, with a 1X mix it simulates for a combustion.

Hi everyone!

Do you control the volume of gas you inject inside the chamber?

The original post wrote:The fuel meter consists of the valve on the fuel canister, a regulator, meter pipe and ball valve.
There's plenty of information on fuel meters in the wiki if you're curious.

Fantastic, I love the breech loading mechanism, and the gun's got a steampunk-looking style too! And that's one of the best damage vids I've seen. Great work!
